Geoharzard Data Acquisition
Risks to hydrocarbon exploration and production as a result of geohazards on and below the seafloor can be reduced through the application of high resolution subsea surveying.
In alliance with our technical partners and the client, Subseaquest provides tools to identify conditions at the seabed where hazardous subsurface features or unstable soil conditions may exist. We work with the client on a customized suite of sensors deployed by Autonomous Underwater Vehicle (AUV) to provide data required for the identification of potential geohazards such as landslides, debris flows, shallow gas accumulation, faults, mud volcanoes, and methane hydrates. Also assessed are shallow subsurface geologic hazards such as buried channels, abnormal pressure zones and synthetic hazards such as pipelines, wellheads, shipwrecks, and debris from offshore operations.
Pipeline geographical position
Start of pipeline coordinates showing bearing and distance of each segment of the line, radii, pipeline crossing coordinates and end of pipelines coordinates. Pipeline orientation and gradient, pipeline depth of burial, and water depths along pipeline. Visual physical condition including identification and location of pertinent pipeline features, Pipeline movement or physical damage.
